Erina was first seen searching for her lost Axew in Gear Station. Eventually, she asked Cilan for help as he gathered stamps. He accompanied her on her search, and they eventually found a note posted as a clue to Axew's location, which had been left by Iris and Ash. Cilan then asked Emmet and Ingo to help them track down Axew's location. They quickly locate Axew, who was reunited with Erina.

However, with all of the time spent searching for Axew, Cilan had failed to collect all of the stamps he needed to battle Ingo and Emmet, his goal throughout the episode. Erina allowed him to have her stamp sheet, which had the stamp required to fill in for the one he needed. She then watched the battle alongside Iris, and afterwards, the four of them rode the Ferris wheel together.

Pokémon

Axew ♀

Axew was somehow separated from Erina and was found by Ash who mistook her for Iris's Axew. The only way she could be told apart was the pink bow on her tail. She then stuck with Iris and Ash who wanted to help her find her Trainer. She accidentally mistook another Trainer to be Erina and ended up being tied up by her Swadloon. In the end, Axew was reunited with her Trainer.
